PS Whilst on the topic of Space. Did anyone else see the news last week about
Spaceport Cornwall? There's some interesting (& numerous) articles if you search the Interwebs - too many to list on here, but basically iirc Cornwall is projected to be a horizontal space port and another in the Highlands for vertical.
The concept of being able to get to Aus in 90 mins is incredible, but I must admit I couldn't help but think it would take so much longer than that to get to Cornwall
